This study aims to isolate and characterize microorganisms that are capable of degrading polycyclic aromatic hydrocarbons (PAHs) from soil samples collected from the dump yard in Tirupur City, an industrial area known for its significant PAH contamination. Using enrichment culture techniques, bacterial strain was isolated. Minimal media with Naphthalene as a carbon source was used to isolate bacteria that exhibited the ability to utilize PAH as their sole carbon and energy source. Morphological, biochemical and molecular methods were performed to identify the isolated strains. Findings revealed that the isolated strains were Sphingomonas paucimobilis which was known for its hydrocarbon-degrading capabilities. This bacterial strain was then grown on different concentrations to evaluate the degradation ability. These strains demonstrated significant PAH degradation efficiency, highlighting their potential application in bioremediation strategies for PAH-contaminated sites. This study provides a valuable insight into the microbial diversity present in PAH-contaminated soils and underscores the importance of bioremediation as a sustainable approach for mitigating environmental pollution.
